EL-9004 Smart Flow Totalizer

■Product descriptionEL-9004 series flow totalizer using advanced production technology, it can on-site temperature, pressure, flow and other signals to collect, display, remote, communication, with the host computer data acquisition system for liquid, General gas, superheated steam, saturated steam and other flow total measurement, with a strong anti-jamming capability.

■Product FeaturesOne. Dual-screen LED digital display, with a very wide display measurement range, can display five instantaneous flow, temperature, pressure, heat, frequency, eleven flow integration, 0.2% of the flow measurement accuracy.Two. Can be used with a variety of flowmeter, free to choose a variety of flow calculation compensation for the flow of high-precision integration.Three. Only automatic compensation function, but also in the temperature, pressure signal abnormalities when the choice of manual value compensation operation.Four. Reliable power-on reset and power-down data protection to ensure that data is not lost after power failure.Five. Can support RS485 communication function, RS232C serial port printing.
